Abstract
PURPOSE: To prevent vibration sounds at the end of cleaning blade from occurring and increase the cleaning effect, by forming a slit at the end of cleaning member pressed against the surface if electrostatic latent image carrier.
CONSTITUTION: A cleaning blade 22 is constituted with an elastic material having an edge at the end thereof, and is installed so that the end may be directed in the same direction as the moving direction of the surface of a photosensitive drum 1. A slit 27 is formed in the part 22a opposing to the cleaned part of the photosensitive drum 1. The two blade parts 22b, 22c divided by this slit 27 are pressurized so as to contact closely with each other. The natural frequency of the blade 22 determined by 22b is abruptly damped because of the contact of the blade part 22c having a different natural frequency. Therefore, occurrence of vibration sounds may be prevented.
